GARLIC-MACHINE.

\ Specification of Letters Patent No. 3,367, dated. December 5,; 1843.

To all whom, it may concern:

Be it known that I, SAMUEL Fluinnnnof near Boonsboro, WVashington county, State of Maryland, have invented anewand useful Machine for Separating Garlic from lVheat, which is described as follows, reference being had to the annexed drawings of the same, making part of this specification.

Figure l is a top view. Fig. 2 is a vertical transverse section at the line as a; of Fig. 1. Fig. 3 is a. plan of one of the serrated plates. l i

This machine consists of a-horizontal revolving axle A, on whichare placed and secured a number of circular disks B, a number of circular plates C notched or serrated on their peripheries resembling circular saws, and a. number of circular rings D arranged in the following manner. A shouL der is formed on the shaft or axle. One of the circular disks B, perforated, in the center with an aperture the diameter x of the smaller part of the shaftis put on the shaft against said shoulder. Then one of the rings D is put on. the I shaft againstsaid plate; then a toothed plate C; then another ring D; then a disk B; then a ring D; then another toothed plate G and soon until a sufficient number of said toothed plates or disks are added; then ahub or collar E is put on the shaft and brought firmly against the outer disk of theseries and secured by a pin F passed through the shaft; this holds them all firmly on the shaft. The shaft is supported in a suitable frame Gof'the requisite size and materialfor the purpose intended. On the outer endof the shaft is a pulley H by which it is turned. In each space between every pair of disks inwhich a toothed plate is arranged is brought the lower end ends of the spring bars nearer to, or remove ing them farther from the teeth of the serrated plates and increasing the strength of the spring.

The spring bars are held against a 1netallic plate T by a staple U inserted into said plate which plate is held in a vertical position by means of two horizontal parallel studs or supportsproject-ing from the frame, saidplate with the springs being brought nearerto. serratedplatesby nuts N on said studs. :Beneath the revolving shaft and serrated plates is arrangeda coarse rack 0 upon one of the cross timbers of the frame. The teeth of the serrated plates pass or revolve in the spaces of said rack. This rack scrapes off the wheat from theteeth of the serrated plates while it allows'the garlic to pass through the spaces between thebars of said rack, these being sufficiently large for that purpose. In the rear of and about the middle of the aforesaid revolving shaft and plates and disks, is arranged another rack P or comb in which the teeth of the serrated plates revolve and by which they are cleaned of the garlic adhering to theteeth. Above the disk and serrated plates is arranged a suitable hopper Q for conducting the grain and garlic to the teeth of the ser rated plates and between them and the spring bars where the garlic is caused to adhere to the teeth. The shaft is turned by any convenient power applied to the pulley H on the end ofthe same. The diameter of the serrated plates is less thanthe diameter of the circular disks and greater than that. of the rings between which they are placed thus forming circular channels or grooves for recelvlng the grain and garlic to be separated by the teeth of the serrated plates. These channels or grooves are colored dark in the drawingFig. 1.

The operation oft-he machine is as follows: The machine being put in motion the wheat and garlic to be separated are put into the hopper Q and by it conducted to the circular grooves orchannels and spaces between the teeth of the notched plates C and the large or lower ends of the springbarsI when the garlic andwheat become jammed board R of the frame while the wheat re-.

sists the teeth, pushes the springs back or causes them to contract and thus open a space between them and the teeth sufficiently large to admit or allow the wheat to descend and fall into the space in front of the aforesaid dividing board and thus the heretofore very difficult and almost impracticable operation of separating garlic from wheat, is efiected.

Whenever it is desired to diminish the space between the lower ends of the spring bars and the teeth the bar L into which the rods M are inserted is depressed which draws the upper ends of the spring bars I outward and forces the lower ends inward toward the teeth. By raising the aforesaid bar an opposite result is produced. This operation also increases or diminishes the stiffness of the spring bars I. The spring bars I are also removed nearer to or farther from the teeth of the plate C by moving the plate T to which the springs are attached, on the studs S by turning the nuts N. What I claim as my invention and which 20 f I desire to secure by Letters Patent is- The aforesaid combination of the disks B toothed or serrated circular plates C spring bars I and combs O, P for separating the garlic from the wheat with which it is 25 found intermixedas set forth.
